BOX-COVER- FASTENER.

Application led October 27, i922. Serial No. 5S7,321.

To all whom t may Iconcern: Y

Be it known that l, HENRYVAPP'EL, a lcitizen of the United States,residing at Plainview, in the county of Wabasha and State of Minnesota,have invented certain new and useful Improvements in Box-CoverFasteners, of which the following is a specification.

This invention relates to new and useful improvements in box coverfasteners.

One object of my invention is to provide simple and eicient means whichmay be employed as a permanent fastener for the box lid or cover, butwhich may be released by the operator to permit the removal of thecover.

Other objects of my invention will appear as the nature of the same isbetter understood, reference being had to the accompanying drawingsforming a part of this application in which- Figure l is a sideelevation illustrating the application of my invention.

Figure 2 is a reverse or bottom plan view of the cover.

Figure 3 is a central longitudinal sectional view of Figure l.

Figure 4 is an end view and,

Figure 5 a detail perspective View of one of the fastening bolts.

Referring to the drawings for a more particular description of myinvention and in which drawings like parts are designated by likereference characters throughout the several views, A designates arectangular box, of any desired type, shape or size, B the lid or coverand O my improved fastening means, as a whole. The cover B is provide onits bottom face at opposite ends with the transverse cleats or strips 1which, as shown, fit against the end walls 2 of the box, the purpose ofwhich will be apparent.

Depending loop shaped clips 3 are carried by the strips ,l and thelatter formed in their bottom edges with central notches or ref cesses 4to accommodate said clips. The end walls 2 of the box are also providedwith Vcross bars or strips 5 on which the strips l rest and said strips5 carry the vertically disposed fastening bolts 6 formed at ,their upperends with the outwardly and downwardly curved or bent heads 7 adapted tohook over the clips 3 when the lid or cover is mounted in position. Thelower .ends of the fastening bolts 6 project below the cross screwing onthe lower threaded vendsfofthe.

fastening bolts.

Other smaller or secondary coil springs 1l are arranged at right angleswith the fastening bolts 6 with their inner ends seating incorresponding recesses or sockets l2 fo-rmed in the outer faces of theend walls 2 of the box and their outer ends bearing against the upperends of the fastening bolts. These springs assist in holding the upperends of the fastening bolts against casual disengagement with the clips.

Through the use of my invention, the box lid or cover may be quicklyapplied to the box andv cannot become unfastened without firstprojecting the vfastening bolts against the tension of the coil springs8 and then turning the bolts to disengage the hooks i with the clips. i

The lower ends of the fastening bolts are provided with transverseopenings a for the purpose of sealing the attachment by small wires (notshown) which are inserted through the bolts and the clips.

From the foregoing description taken in connection with the drawings, itis thought that the construction, operation and advantages of myinvention will be readily understood without requiring a more extendedexplanation. y

Various changes in the form, proportions and minor details o-fconstruction may bel resorted to without departing from the principle orsacrificing any of the advantages of my invention as defined lin theappended claims.

v Having described my invention', what I claim as new and desire tosecure by Letters Patent, is y Vl. A. box cover fastener comprisingclips depending from thercover and spring retracted fasteningboltscarried by thebox and provided at their upper end with hooks adapted tolengage said clipswhen the 'cover is in position, and other smaller orsecondary springs arranged at right angles with the fastening bolts withtheir outer ends engagends of the box and provided at their upper endswith outwardly bent hooks; adapted to hook over or engage said clips andother smaller springs arranged in a horizontal vplane With their outerends bearing against the upper ends of the fastening hooks.
